Kurzweil received the 1999 National Medal of Technology and Innovation, the United States' highest honor in technology, from President Clinton in a White House ceremony. He was the recipient of the $500,000 Lemelson-MIT Prize for 2001,[6] the world's largest for innovation. And in 2002 he was inducted into the National Inventors Hall of Fame, established by the U.S. Patent Office. He has received twenty honorary doctorates, and honors from three U.S. presidents. Kurzweil has been described as a "restless genius"[7] by The Wall Street Journal and "the ultimate thinking machine"[8] by Forbes. PBS included Kurzweil as one of 16 "revolutionaries who made America"[9] along with other inventors of the past two centuries. Inc. magazine ranked him #8 among the "most fascinating" entrepreneurs in the United States and called him "Edison's rightful heir".[10]

Ray Kurzweil grew up in the New York City borough of Queens. He was born to secular Jewish parents who had emigrated from Austria just before the onset of World War II. He was exposed via Unitarian Universalism to a diversity of religious faiths during his upbringing. His unitarian church had the philosophy of many paths to the truth – the religious education consisted of spending six months on a single religion before moving onto the next. Kurzweil is an agnostic.[13] His father was a musician, a noted conductor, and a music educator. His mother was a visual artist. Kurzweil decided he wanted to be an inventor at the age of five.[14] In his youth, Kurzweil was an avid reader of science fiction literature. At the age of eight, nine, and ten, he read the entire Tom Swift Jr. series. At the age of seven or eight, he built a robotic puppet theater and robotic game. He was involved with computers and built computing devices by the age of twelve. At the age of fourteen, Kurzweil wrote a paper detailing his theory of the neocortex.[15] His parents were involved with the arts, and he is quoted in the documentary Transcendent Man as saying that the household always produced discussions about the future and technology.

Kurzweil attended Martin Van Buren High School. During class, he often held onto his class textbooks to seemingly participate, but instead, focused on his own projects which were hidden behind the book. His uncle, an engineer at Bell Labs, taught young Kurzweil the basics of computer science.[16] In 1963, at age fifteen, he wrote his first computer program.[17] He created a pattern-recognition software program that analyzed the works of classical composers, and then synthesized its own songs in similar styles. In 1965, he was invited to appear on the CBS television program I've Got a Secret, where he performed a piano piece that was composed by a computer he also had built.[18] Later that year, he won first prize in the International Science Fair for the invention;[19] Kurzweil's submission to Westinghouse Talent Search of his first computer program alongside several other projects resulted in him being one of its national winners, which allowed him to be personally congratulated by President Lyndon B. Johnson during a White House ceremony. These activities collectively impressed upon Kurzweil the belief that nearly any problem could be overcome.[20]

While in high school, Kurzweil had corresponded with Marvin Minsky and was invited to visit him at MIT, which he did. Kurzweil also visited Professor Rosenblatt at Cornell.[21]

He obtained a B.S. in computer science and literature in 1970 at MIT. He went to MIT to study with Marvin Minsky. He took all of the computer programming courses (eight or nine) offered at MIT in the first year and a half.

In 1968, during his sophomore year at MIT, Kurzweil started a company that used a computer program to match high school students with colleges. The program, called the Select College Consulting Program, was designed by him and compared thousands of different criteria about each college with questionnaire answers submitted by each student applicant. Around this time, he sold the company to Harcourt, Brace & World for $100,000 (roughly $670,000 in 2013 dollars) plus royalties.[22]

In 1974, Kurzweil founded Kurzweil Computer Products, Inc. and led development of the first omni-font optical character recognition system, a computer program capable of recognizing text written in any normal font. Before that time, scanners had only been able to read text written in a few fonts. He decided that the best application of this technology would be to create a reading machine, which would allow blind people to understand written text by having a computer read it to them aloud. However, this device required the invention of two enabling technologies—the CCDflatbed scanner and the text-to-speech synthesizer. Development of these technologies was completed at other institutions such as Bell Labs, and on January 13, 1976, the finished product was unveiled during a news conference headed by him and the leaders of the National Federation of the Blind. Called the Kurzweil Reading Machine, the device covered an entire tabletop.

Kurzweil's next major business venture began in 1978, when Kurzweil Computer Products began selling a commercial version of the optical character recognition computer program. LexisNexis was one of the first customers, and bought the program to upload paper legal and news documents onto its nascent online databases.

Kurzweil sold his company to Lernout & Hauspie. Following the bankruptcy of the latter, the system became a subsidiary of Xerox formerly known as Scansoft and now as Nuance Communications, and he functioned as a consultant for the former until 1995.

Kurzweil's next business venture was in the realm of electronic music technology. After a 1982 meeting with Stevie Wonder, in which the latter lamented the divide in capabilities and qualities between electronic synthesizers and traditional musical instruments, Kurzweil was inspired to create a new generation of music synthesizers capable of accurately duplicating the sounds of real instruments. Kurzweil Music Systems was founded in the same year, and in 1984, the Kurzweil K250 was unveiled. The machine was capable of imitating a number of instruments, and in tests musicians were unable to discern the difference between the Kurzweil K250 on piano mode from a normal grand piano.[23] The recording and mixing abilities of the machine, coupled with its abilities to imitate different instruments, made it possible for a single user to compose and play an entire orchestral piece.

Kurzweil Music Systems was sold to Korean musical instrument manufacturer Young Chang in 1990. As with Xerox, Kurzweil remained as a consultant for several years. Hyundai acquired Young Chang in 2006 and in January 2007 appointed Raymond Kurzweil as Chief Strategy Officer of Kurzweil Music Systems.[24]

Concurrent with Kurzweil Music Systems, Kurzweil created the company Kurzweil Applied Intelligence (KAI) to develop computer speech recognition systems for commercial use. The first product, which debuted in 1987, was an early speech recognition program.

Kurzweil started Kurzweil Educational Systems in 1996 to develop new pattern-recognition-based computer technologies to help people with disabilities such as blindness, dyslexia and ADD in school. Products include the Kurzweil 1000 text-to-speech converter software program, which enables a computer to read electronic and scanned text aloud to blind or visually impaired users, and the Kurzweil 3000 program, which is a multifaceted electronic learning system that helps with reading, writing, and study skills.

During the 1990s, Kurzweil founded the Medical Learning Company.[25] The company's products included an interactive computer education program for doctors and a computer-simulated patient. Around the same time, Kurzweil started KurzweilCyberArt.com—a website featuring computer programs to assist the creative art process. The site used to offer free downloads of a program called AARON—a visual art synthesizer developed by Harold Cohen—and of "Kurzweil's Cybernetic Poet", which automatically creates poetry. During this period he also started KurzweilAI.net, a website devoted towards showcasing news of scientific developments, publicizing the ideas of high-tech thinkers and critics alike, and promoting futurist-related discussion among the general population through the Mind-X forum.

In 1999, Kurzweil created a hedge fund called "FatKat" (Financial Accelerating Transactions from Kurzweil Adaptive Technologies), which began trading in 2006. He has stated that the ultimate aim is to improve the performance of FatKat's A.I. investment software program, enhancing its ability to recognize patterns in "currency fluctuations and stock-ownership trends."[26] He predicted in his 1999 book, The Age of Spiritual Machines, that computers will one day prove superior to the best human financial minds at making profitable investment decisions. In June 2005, Kurzweil introduced the "Kurzweil-National Federation of the Blind Reader" (K-NFB Reader)—a pocket-sized device consisting of a digital camera and computer unit. Like the Kurzweil Reading Machine of almost 30 years before, the K-NFB Reader is designed to aid blind people by reading written text aloud. The newer machine is portable and scans text through digital camera images, while the older machine is large and scans text through flatbed scanning.

In December 2012, Kurzweil was hired by Google in a full-time position to "work on new projects involving machine learning and language processing".[27] Google co-founder Larry Page and Kurzweil agreed on a one-sentence job description: "to bring natural language understanding to Google".[28]

He received a Technical Grammy on February 8, 2015, recognizing his diverse technical and creative accomplishments. For purposes of the Grammy, perhaps most notable was the aforementioned Kurzweil K250.[29]

Kurzweil married Sonya Rosenwald Fenster in 1975 and has two children.[30] Sonya Kurzweil is a psychologist in private practice and clinical instructor in Psychology at Harvard Medical School; she is interested in the way that digital media can be integrated into the lives of children and teens.[31]

He has a son, Ethan Kurzweil, a venture capitalist,[32] and a daughter, Amy Kurzweil.[33]

Kurzweil said "I realize that most inventions fail not because the R&D department can’t get them to work, but because the timing is wrong - not all of the enabling factors are at play where they are needed. Inventing is a lot like surfing: you have to anticipate and catch the wave at just the right moment."[34][35]

For the past several decades, Kurzweil's most effective and common approach to doing creative work has been conducted during his lucid dreamlike state which immediately precedes his awakening state. He claims to have constructed inventions, solved difficult problems, such as algorithmic, business strategy, organizational, and interpersonal problems, and written speeches in this state.[21]

Kurzweil's first book, The Age of Intelligent Machines, was published in 1990. The nonfiction work discusses the history of computer artificial intelligence (AI) and forecasts future developments. Other experts in the field of AI contribute heavily to the work in the form of essays. The Association of American Publishers' awarded it the status of Most Outstanding Computer Science Book of 1990.[36]

In 1993, Kurzweil published a book on nutrition called The 10% Solution for a Healthy Life. The book's main idea is that high levels of fat intake are the cause of many health disorders common in the U.S., and thus that cutting fat consumption down to 10% of the total calories consumed would be optimal for most people.

In 1999, Kurzweil published The Age of Spiritual Machines, which further elucidates his theories regarding the future of technology, which themselves stem from his analysis of long-term trends in biological and technological evolution. Much emphasis is on the likely course of AI development, along with the future of computer architecture.

The Singularity Is Near, published in 2005, was made into a movie starring Pauley Perrette from NCIS.[37] In February 2007, Ptolemaic Productions acquired the rights to The Singularity is Near, The Age of Spiritual Machines and Fantastic Voyage including the rights to film Kurzweil's life and ideas for the documentary film Transcendent Man, which was directed by Barry Ptolemy.

Transcend: Nine Steps to Living Well Forever,[38] a follow-up to Fantastic Voyage, was released on April 28, 2009.

Kurzweil wrote and co-produced a movie directed by Anthony Waller, called The Singularity Is Near: A True Story About the Future, in 2010 based, in part, on his 2005 book The Singularity Is Near. Part fiction, part non-fiction, he interviews 20 big thinkers like Marvin Minsky, plus there is a B-line narrative story that illustrates some of the ideas, where a computer avatar (Ramona) saves the world from self-replicating microscopic robots. In addition to his movie, an independent, feature-length documentary was made about Kurzweil, his life, and his ideas, called Transcendent Man. Filmmakers Barry Ptolemy and Felicia Ptolemy followed Kurzweil, documenting his global speaking-tour. Premiered in 2009 at the Tribeca Film Festival, Transcendent Man documents Kurzweil's quest to reveal mankind's ultimate destiny and explores many of the ideas found in his New York Times bestselling book, The Singularity Is Near, including his concept exponential growth, radical life expansion, and how we will transcend our biology. The Ptolemys documented Kurzweil's stated goal of bringing back his late father using AI. The film also features critics who argue against Kurzweil's predictions.

The feature-length documentary film The Singularity by independent filmmaker Doug Wolens (released at the end of 2012), showcasing Kurzweil, has been acclaimed as "a large-scale achievement in its documentation of futurist and counter-futurist ideas” and “the best documentary on the Singularity to date."[43]

Kurzweil frequently comments on the application of cell-size nanotechnology to the workings of the human brain and how this could be applied to building AI. While being interviewed for a February 2009 issue of Rolling Stone magazine, Kurzweil expressed a desire to construct a genetic copy of his late father, Fredric Kurzweil, from DNA within his grave site. This feat would be achieved by exhumation and extraction of DNA, constructing a clone of Fredric and retrieving memories and recollections—from Ray's mind—of his father.[44] Kurzweil kept all of his father's records, notes, and pictures in order to maintain as much of his father as he could. Ray is known for taking over 200 pills a day, meant to reprogram his biochemistry. This, according to Ray, is only a precursor to the devices at the nano scale that will eventually replace a blood-cell, self updating of specific pathogens to improve the immune system.[44]

In his 1999 book The Age of Spiritual Machines, Kurzweil proposed "The Law of Accelerating Returns", according to which the rate of change in a wide variety of evolutionary systems (including the growth of technologies) tends to increase exponentially.[45] He gave further focus to this issue in a 2001 essay entitled "The Law of Accelerating Returns", which proposed an extension of Moore's law to a wide variety of technologies, and used this to argue in favor of Vernor Vinge's concept of a technological singularity.[46] Kurzweil suggests that this exponential technological growth is counter-intuitive to the way our brains perceive the world—since our brains were biologically inherited from humans living in a world that was linear and local—and, as a consequence, he claims it has encouraged great skepticism in his future projections.

Kurzweil is working with the Army Science Board to develop a rapid response system to deal with the possible abuse of biotechnology. He suggests that the same technologies that are empowering us to reprogram biology away from cancer and heart disease could be used by a bioterrorist to reprogram a biological virus to be more deadly, communicable, and stealthy. However, he suggests that we have the scientific tools to successfully defend against these attacks, similar to the way we defend against computer software viruses. He has testified before Congress on the subject of nanotechnology, advocating that nanotechnology has the potential to solve serious global problems such as poverty, disease, and climate change. "Nanotech Could Give Global Warming a Big Chill".[47]

In media appearances, Kurzweil has stressed the extreme potential dangers of nanotechnology[18] but argues that in practice, progress cannot be stopped because that would require a totalitarian system, and any attempt to do so would drive dangerous technologies underground and deprive responsible scientists of the tools needed for defense. He suggests that the proper place of regulation is to ensure that technological progress proceeds safely and quickly, but does not deprive the world of profound benefits. He stated, "To avoid dangers such as unrestrained nanobot replication, we need relinquishment at the right level and to place our highest priority on the continuing advance of defensive technologies, staying ahead of destructive technologies. An overall strategy should include a streamlined regulatory process, a global program of monitoring for unknown or evolving biological pathogens, temporary moratoriums, raising public awareness, international cooperation, software reconnaissance, and fostering values of liberty, tolerance, and respect for knowledge and diversity."[48]

Kurzweil admits that he cared little for his health until age 35, when he was found to suffer from a glucose intolerance, an early form of type II diabetes (a major risk factor for heart disease). Kurzweil then found a doctor (Terry Grossman, M.D.) who shares his non-conventional beliefs to develop an extreme regimen involving hundreds of pills, chemical intravenous treatments, red wine, and various other methods to attempt to live longer. Kurzweil was ingesting "250 supplements, eight to 10 glasses of alkaline water and 10 cups of green tea" every day and drinking several glasses of red wine a week in an effort to "reprogram" his biochemistry.[49] Lately, he has cut down the number of supplement pills to 150.[50]

He asserts that in the future, everyone will live forever.[55] In a 2013 interview, Kurzweil said that in 15 years, medical technology could add more than a year to one's remaining life expectancy for each year that passes, and we could then "outrun our own deaths". He has been an extreme advocate of SENS Research Foundation for the successful defeating of aging, and has encouraged acts of donation to hasten their rejuvenation research.[28][56]

According to Kurzweil, technologists will be creating synthetic neocortexes based on the operating principles of the human neocortex with the primary purpose of extending our own neocortexes. He claims to believe that the neocortex of an adult human consists of approximately 300 million pattern recognizers. He draws on the commonly accepted belief that the primary anatomical difference between humans and other primates that allowed for superior intellectual abilities was the evolution of a larger neocortex. He claims that the six-layered neocortex deals with increasing abstraction from one layer to the next. He says that at the low levels, the neocortex may seem cold and mechanical because it can only make simple decisions, but at the higher levels of the hierarchy, the neocortex is likely to be dealing with concepts like being funny, being sexy, expressing a loving sentiment, creating a poem or understanding a poem, etc. He claims to believe that these higher levels of the human neocortex were the enabling factors to permit the human development of language, technology, art, and science. He stated, "If the quantitative improvement from primates to humans with the big forehead was the enabling factor to allow for language, technology, art, and science, what kind of qualitative leap can we make with another quantitative increase? Why not go from 300 million pattern recognizers to a billion?”[57]

In February 2009, Kurzweil, in collaboration with Google and the NASA Ames Research Center, announced the creation of the Singularity University training center for corporate executives and government officials. The University's self-described mission is to "assemble, educate and inspire a cadre of leaders who strive to understand and facilitate the development of exponentially advancing technologies and apply, focus and guide these tools to address humanity's grand challenges".[62] Using Vernor Vinge's Singularity concept as a foundation, the university offered its first nine-week graduate program to 40 students in June, 2009.

Kurzweil's first book, The Age of Intelligent Machines, presented his ideas about the future. It was written from 1986 to 1989 and published in 1990. Building on Ithiel de Sola Pool's "Technologies of Freedom" (1983), Kurzweil claims to have forecast the demise of the Soviet Union due to new technologies such as cellular phones and fax machines disempowering authoritarian governments by removing state control over the flow of information.[63] In the book, Kurzweil also extrapolated preexisting trends in the improvement of computer chess software performance to predict that computers would beat the best human players "by the year 2000".[64] In May 1997, chess World Champion Garry Kasparov was defeated by IBM's Deep Blue computer in a well-publicized chess tournament.[65]

Perhaps most significantly, Kurzweil foresaw the explosive growth in worldwide Internet use that began in the 1990s. At the time of the publication of The Age of Intelligent Machines, there were only 2.6 million Internet users in the world,[66] and the medium was unreliable, difficult to use, and deficient in content. He also stated that the Internet would explode not only in the number of users but in content as well, eventually granting users access "to international networks of libraries, data bases, and information services". Additionally, Kurzweil claims to have correctly foreseen that the preferred mode of Internet access would inevitably be through wireless systems, and he was also correct to estimate that the latter would become practical for widespread use in the early 21st century.

Kurzweil's predictions for 2009 were mostly inaccurate, claims Forbes magazine. For example, Kurzweil predicted, "The majority of text is created using continuous speech recognition." This is not the case.[67]

In 1999, Kurzweil published a second book titled The Age of Spiritual Machines, which goes into more depth explaining his futurist ideas. The third and final part of the book is devoted to predictions over the coming century, from 2009 through 2099. In The Singularity Is Near he makes fewer concrete short-term predictions, but includes many longer-term visions.

He states that with radical life extension will come radical life enhancement. He says he is confident that within 10 years we will have the option to spend some of our time in 3D virtual environments that appear just as real as real reality, but these will not yet be made possible via direct interaction with our nervous system. "If you look at video games and how we went from pong to the virtual reality we have available today, it is highly likely that immortality in essence will be possible." He claims to know that 20 to 25 years from now, we will have millions of blood-cell sized devices, known as nanobots, inside our bodies fighting against diseases, improving our memory, and cognitive abilities. Kurzweil claims to know that a machine will pass the Turing test by 2029, and that around 2045, "the pace of change will be so astonishingly quick that we won't be able to keep up, unless we enhance our own intelligence by merging with the intelligent machines we are creating". Shortly after, Kurzweil claims to know that humans will be a hybrid of biological and non-biological intelligence that becomes increasingly dominated by its non-biological component. He stresses that "AI is not an intelligent invasion from Mars. These are brain extenders that we have created to expand our own mental reach. They are part of our civilization. They are part of who we are. So over the next few decades our human-machine civilization will become increasingly dominated by its non-biological component. In Transcendent Man Kurzweil states "We humans are going to start linking with each other and become a metaconnection we will all be connected and all be omni-present, plugged into this global network that is connected to billions of people, and filled with data." [68] Kurzweil states in a press conference that we are the only species that goes beyond our limitations- "we didn't stay in the caves, we didn't stay on the planet, and we're not going to stay with the limitations of our biology". In his singularity based documentary he is quoted saying "I think people are fooling themselves when they say they have accepted death".

In 2008, Kurzweil said in an expert panel in the National Academy of Engineering that solar power will scale up to produce all the energy needs of Earth's people in 20 years. According to Kurzweil, we only need to capture 1 part in 10,000 of the energy from the Sun that hits Earth's surface to meet all of humanity's energy needs.[69]

Kurzweil was referred to as "the ultimate thinking machine" by Forbes[8] and as a "restless genius"[7] by The Wall Street Journal. PBS included Kurzweil as one of 16 "revolutionaries who made America"[9] along with other inventors of the past two centuries. Inc. magazine ranked him #8 among the "most fascinating" entrepreneurs in the United States and called him "Edison's rightful heir".[10]

Kurzweil has received many awards and honors, including:

First place in the 1965 International Science Fair[19] for inventing the classical music synthesizing computer.

In 1986, Kurzweil was named Honorary Chairman for Innovation of the White House Conference on Small Business by President Reagan

In 1988, Kurzweil was named Inventor of the Year by MIT and the Boston Museum of Science.[72]

In 1990, Kurzweil was voted Engineer of the Year by the over one million readers of Design News Magazine and received their third annual Technology Achievement Award[72][73]

The 1994 Dickson Prize in Science. One is awarded every year by Carnegie Mellon University to individuals who have "notably advanced the field of science." Both a medal and a $50,000 prize are presented to winners.[74]

The 1999 National Medal of Technology.[76] This is the highest award the President of the United States can bestow upon individuals and groups for pioneering new technologies, and the President dispenses the award at his discretion.[77] Bill Clinton presented Kurzweil with the National Medal of Technology during a White House ceremony in recognition of Kurzweil's development of computer-based technologies to help the disabled.

The 2000 Telluride Tech Festival Award of Technology.[78] Two other individuals also received the same honor that year. The award is presented yearly to people who "exemplify the life, times and standard of contribution of Tesla, Westinghouse and Nunn."

The 2001 Lemelson-MIT Prize for a lifetime of developing technologies to help the disabled and to enrich the arts.[79] Only one is awarded each year - it is given to highly successful, mid-career inventors. A $500,000 award accompanies the prize.[80]

Kurzweil was inducted into the National Inventors Hall of Fame in 2002 for inventing the Kurzweil Reading Machine.[81] The organization "honors the women and men responsible for the great technological advances that make human, social and economic progress possible."[82] Fifteen other people were inducted into the Hall of Fame the same year.[83]

The Arthur C. Clarke Lifetime Achievement Award on April 20, 2009 for lifetime achievement as an inventor and futurist in computer-based technologies.[84]

In 2013, Kurzweil was honored as a Silicon Valley Visionary Award winner on June 26 by SVForum[86]

In 2014, Kurzweil was honored with the American Visionary Art Museum’s Grand Visionary Award on January 30.[87][88][89]

Kurzweil has received 20 honorary doctorates in science, engineering, music and humane letters from Rensselaer Polytechnic Institute, Hofstra University and other leading colleges and universities, as well as honors from three U.S. presidents - Clinton, Reagan and Johnson.[5][90]

Kurzweil has received seven national and international film awards including the CINE Golden Eagle Award and the Gold Medal for Science Education from the International Film and TV Festival of New York.[72]

Daniel Lyons, writing in Newsweek, criticized Kurzweil for some of his predictions that turned out to be wrong, such as the economy continuing to boom from the 1998 dot-com through 2009, a US company having a market capitalization of more than $1 trillion, a supercomputer achieving 20 petaflops, speech recognition being in widespread use and cars that would drive themselves using sensors installed in highways; all by 2009.[98] To the charge that a 20 petaflop supercomputer was not produced in the time he predicted, Kurzweil responded that he considers Google a giant supercomputer, and that it is indeed capable of 20 petaflops.[98]

In the cover article of the December 2010 issue of IEEE Spectrum, John Rennie criticizes Kurzweil for several predictions that failed to become manifest by the originally predicted date. "Therein lie the frustrations of Kurzweil's brand of tech punditry. On close examination, his clearest and most successful predictions often lack originality or profundity. And most of his predictions come with so many loopholes that they border on the unfalsifiable."[99]

Bill Joy, cofounder of Sun Microsystems, agrees with Kurzweil's timeline of future progress, but thinks that technologies such as AI, nanotechnology and advanced biotechnology will create a dystopian world.[100]Mitch Kapor, the founder of Lotus Development Corporation, has called the notion of a technological singularity "intelligent design for the IQ 140 people...This proposition that we're heading to this point at which everything is going to be just unimaginably different—it's fundamentally, in my view, driven by a religious impulse. And all of the frantic arm-waving can't obscure that fact for me."[101]

Some critics have argued more strongly against Kurzweil and his ideas. Cognitive scientist Douglas Hofstadter has said of Kurzweil's and Hans Moravec's books: "It's an intimate mixture of rubbish and good ideas, and it's very hard to disentangle the two, because these are smart people; they're not stupid."[102] Biologist P. Z. Myers has criticized Kurzweil's predictions as being based on "New Age spiritualism" rather than science and says that Kurzweil does not understand basic biology.[103][104] VR pioneer Jaron Lanier has even described Kurzweil's ideas as "cybernetic totalism" and has outlined his views on the culture surrounding Kurzweil's predictions in an essay for Edge.org entitled One Half of a Manifesto.[43][105]

In a critical review of Kurzweil's book How to Create a Mind: The Secret of Human Thought Revealed, philosopher Colin McGinn refers to "the hype so blatantly brandished in its title" and asks: "He is clearly a man of many parts—but is ultimate theoretician of the mind one of them?" McGinn calls Kurzweil's claim that pattern recognition is the key to mental phenomena "obviously false" and concludes that the book is "interesting in places, fairly readable, moderately informative, but wildly overstated".[106]

John Gray, the British philosopher, argues that contemporary science is what magic was for ancient civilizations. It gives a sense of hope for those who are willing to do almost anything in order to achieve eternal life. He quotes Kurzweil's Singularity as another example of a trend which has almost always been present in the history of mankind.[107]

Nassim Nicholas Taleb, Lebanese American essayist, scholar and statistician, criticized his approach of taking multiple pills to achieve longevity in his book Antifragile.

My thoughts are more in line with those of Jaron Lanier, who points out that while hardware might be getting faster all the time, software is shit (I am paraphrasing his argument).

He's right. I, for one, do see such a flaw, and I expect Dawkins and Hofstadter would say the same.

^Allen, Paul. "The Singularity Isn't Near". Technology Review. Kurzweil's reasoning rests on the Law of Accelerating Returns and its siblings, but these are not physical laws. They are assertions about how past rates of scientific and technical progress can predict the future rate. Therefore, like other attempts to forecast the future from the past, these "laws" will work until they don't.

During the height of the dotcom boom in 1998, Kurzweil predicted that the economy would keep on booming right through 2009 and that at least one U.S. company would have a market capitalization of more than $1 trillion, neither of which occurred. Kurzweil also predict-ed that by 2009 a top supercomputer would be capable of performing 20 petaflops, the same as the human brain. In fact, the top supercomputer at the time, the IBM Roadrunner, was capable of only 1.456 petaflops mark. Kurzweil also predicted that by now our cars would be able to drive themselves by communicating with intelligent sensors embedded in highways, and that speech recognition would be in widespread use.

Still, a lot of people think Kurzweil is completely bonkers and/or full of a certain messy byproduct of ordinary biological functions. They include P. Z. Myers, a biologist at the University of Minnesota, Morris, who has used his blog to poke fun at Kurzweil and other armchair futurists who, according to Myers, rely on junk science and don't understand basic biology. "I am completely baffled by Kurzweil's popularity, and in particular the respect he gets in some circles, since his claims simply do not hold up to even casually critical examination," writes Myers. He says Kurzweil's Singularity theories are closer to a deluded religious movement than they are to science. "It's a New Age spiritualism—that's all it is," Myers says. "Even geeks want to find God somewhere, and Kurzweil provides it for them."
